Bad Request (400) and 502 error: Nginx, gunicorn, django

I'm trying to deploy my site using nginx, gunicorn, and django.

When I run gunicorn and load the page at first I was getting a 502 Bad gateway error then I switch the server name to the IP address of my server and now I get a Bad Request 400 error or the domain is unable to be found.

I've been following these steps from Test Driven Development.

I realized last night that I was using my staging server to update my live domain instead of a staging domain. So I created a staging domain as a subdomain of the live domain and created a separate directory for it, then git pulled down the work I had done previously, but it's not working.

My nginx conf file:

 server {
     listen 80;
     server_name my-server-ip-address;

     location / {
          proxy_set_header Host $host;
          proxy_pass http://unix:/tmp/mysitename.socket;
     }

      location /static {
         autoindex on;
         root /home/cmac/sites/mysitename/;
     }

 }

Nginx Error log:

2015/04/11 18:59:16 [error] 18650#0: *494 connect() to unix:/tmp/mysitename.socket failed (111: Connection refused) while connecting to upstream

My settings.py:

 DEBUG = False

 TEMPLATE_DEBUG = DEBUG

 ALLOWED_HOSTS = [mysitename]

When I run gunicorn:

 [2015-04-11 20:40:39 +0000] [4174] [INFO] Starting gunicorn 19.3.0
 [2015-04-11 20:40:39 +0000] [4174] [INFO] Listening at:      http://127.0.0.1:8000 (4174)

 [2015-04-11 20:40:39 +0000] [4177] [INFO] Booting worker with pid: 4177

Things were working before I decided to switch domains.

Edit whole nginx.conf file

In mysitename you need to listen on port 80, and server_name as your your staging domain like staging.example.com, also do not use unix sock at the moment, put http://127.0.0.1:8000 in proxy_pass as where your gunicorn serves. Try also comment out the server block in your nginx.conf, it has conflicts with your mysitename.

Also, are you sure user cmac has permissions under your directory/files? normally it runs on www-data.

Hope this helps.
